10 Claims, No Drawings l-TRlTYL-l ,2 ,4-TRIAZOLES The present invention relates to and has forits objects the provision for particular new l-trityl-l,2,4- triazoles, i.e. l-[(optionally mono and di chloro-, fluoro-, cyanoand trifluoromethylsubstituted)-(optionally mono and di chloro-, fluoro-, cyanoand trifluoromethylsubstituted)-(optionally mono and di chloro-, fluoro, cyano and trifluoro-methylsubstituted)-trityl]-3-(optionally chloro substituted)-5- (optionally chloro substituted)-1,2,4-triazoles, or 1- [(optionally mono and di chloro-, fluoro-, cyanoand trifluoro-methylsubstituted phenyl)-(optionally mono and di chloro-, fluoro-, cyanoand trifluoromethylsubstituted phenyl)-(optionally mono and di chloro-, fluoro-, cyanoand trifluoromethyl-substituted phenyl)-methyl]-3-(optionally chloro-substituted)-5-(optionally chloro-substituted)-l,2,4-triazoles, which possess fungicidal properties, active compositions in the form of mixtures of such compounds with solid and liquid dispersible carrier vehicles, and methods for producing such compounds and for using such compounds in a new way especially for combating fungi, with other and further objects becoming apparent from a study of the within specification and accompanying examples.

It is known that certain N-tritylimidazoles, such as N- tritylimidazole (A) per se, exhibit fungitoxic properties (compare US. Pat. No. 3,321,366).

It has now been found, in accordance with the present invention, that the particular new l-trityl-l ,2,4- triazoles of the formula in which X each individually is hydrogen, or chloro, and R, R and R" each individually is phenyl, chlorophenyl, dichlorophenyl, fluorophenyl, cyanophenyl, or trifluoromethylphenyl, and the corresponding hydrochloric acid and lactic acid salts thereof, exhibit strong fungicidal properties.

It has been furthermore found, in accordance with the present invention, that the particular new compounds of formula (I) above may be produced by the process which comprises reacting a trityl halide of the formula Hal R-b-R" in which R, R and R are the same as defined above, and Hal is halo, such as chloro, bromo, iodo or fluoro,

especially chloro, with a 1,2,4-triazole of the formula (III) in which X each individually is the same as defined above, in a polar, inert organic solvent at a temperature of from about 0 to l00 C in the presence of an acidbinding agent.

Optionally, the l,2,4-triazoles so obtained are reacted with organic or inorganic acids, e.g. lactic acid or hydrochloric acid, to give the appropriate salts.

It is very surprising that the specific l-trityl-l,2,4-

' triazoles of formula (I) according to the present invention, and their salts of organic and inorganic acids, e.g. the lactate and hydrochloride salts, have a considerably stronger fungitoxic activity, in particular against the causative organisms of powdery mildew of apples .-(Podosphaera leucotricha Salm.), than the previously known N-tritylimidazoles, such as N-tritylimidazole (A) per se. The active compounds according to the ,present invention therefore represent a valuable conitribution to the art.

The course of the production reaction according to the present invention is illustrated by the following equation:

(IIIa) trifluoromethylphenyl such as 2-, 3- and 4- trifluoromethylphenyl, especially 3- trifluoromethylphenyl;

'zwith the proviso that the corresponding compounds having the above defined symbols may also be present in the form of theirorganic and inorganic salts, such as the lactic acid salts and the hydrochloric acid salts thereof.

Preferably, each X individually is hydrogen; or chloro; R is phenyl; or chlorophenyl; or dichlorophenyl', or fluorophenyl; or cyanophenyl; or trifluoromethylphenyl; and R and R" are phenyl; or chlorophenyl; with the proviso that the corresponding compounds also include the lactate and hydrochloride salts thereof.

In particular, one X is hydrogen and the other X is hydrogen or chloro; R is phenyl; or chlorophenyl; or 2,4-dichlorophenyl; or 4-fluorophenyl; or cyanophenyl; or 3-trifluoromethylphenyl; and R and R" are phenyl;

or 4-chlorophenyl; with the proviso that the corresponding compounds also include the lactate and hydrochloride salts thereof when X is hydrogen; R is phenyl; or chlorophenyl; or 2,4-dichlorophenyl; and R and R" are phenyl.

The trityl halides required as starting materials are clearly characterized by formula (II) above.

In this regard, such trityl halides required as starting materials are known in part. The new starting trityl halides can be prepared in the same manner as the already known ones.

Preparation of these can for example be carried out as follows:

a. First, a Grignard compound of monoor disubstituted benzene is prepared in the known manner. The substituted phenylmagnesium bromide so obtained is then reacted with (the corresponding optionally substituted) benzophenone.

b. The organometallic complex compound thus obtained is subjected to hydrolysis, the appropriate carbinol being formed (compare J. Org. Chem. 7, 392 (1942)).

c. From the carbinol, the chloride can be obtained in simple manner when the carbinol is reacted with anhydrous hydrogen chloride or with thionyl chloride. The hydroxyl group is replaced by chlorine (compare J. Org. Chem. 7, 392 (1942)).

The triazoles also required as starting materials are clearly characterized by the formula (III) above.

These starting triazoles are likewise largely known. The hitherto unknown compounds can be prepared in the same manner as the known triazoles.

For the instant reaction of trityl halides with 1,2,4- triazoles, polar inert organic solvents are advantageously used. These include, for example, nitriles, such as acetonitrile; sulfoxides, such as dimethyl sulfoxide; formamides, such as dimethyl formamide; ketones, such as acetone; ethers, such as diethyl ether; nitroalkanes, such as nitromethane; and other substituted hydrocarbons, such as for example chloroform; and the like. Particularly suitable are polar inert solvents which have a dielectric constant of more than 2.4.

The production reaction is carried out in the presence of an acid-binding agent. Preferably, a suitable excess of tertiary amine, such as, for example, triethylamine or dimethylbenzyl-amine, is used. However, an excess of the starting 1,2,4-triazole may also be employed, or other customarily used organic acid-binding agents.

The production reaction temperatures can be varied within a fairly wide range. In general, the work is carried out at substantially between about l00 C, preferably between about 50-90 C.

When carrying out the process according to the present invention, the starting materials may be used in the molar ratio of 11121 with the acid-binding agent. The reaction time depends on the reaction temperature and is generally between about 3 and 24 hours. In the working up of the reaction mixture, the solvent is removed and the reaction product is freed from amine hydrochloride by washing with water or, if the amine hydrochloride is sparingly soluble in water, separated from the hydrochloride with an organic solvent.

Advantageously, the active compounds according to the present invention exhibit a strong fungitoxic activity, and are distinguished by a broad spectrum of activity. Their low toxicity to warm-blooded animals and their good compatibility with higher plants permits the use of the instant compounds as crop protection agents against fungal diseases.

In the concentrations necessary for the control of fungi, it will be appreciated that the instant active compounds do not damage cultivated plants.

Fungitoxic agents in crop protection as contemplated herein are used for the control of fungi from the most diverse classes of fungi, such as Archimycetes, Phycomycetes, Ascomycetes, Basidiomycetes and Fungi Imperfecti.

The active compounds according to the present invention can be used against parasitic fungi on abovethe-soil parts of plants, fungi which cause tracheomycosis, which attack the plant from the soil, seedborne fungi and soil-inhabiting fungi. Such compounds are particularly effective against fungi which cause powdery mildew diseases. This group of fungi includes predominantly representatives from the family of the Erysiphaceae with the most important genera Erysiphe, Uncinula (Oidium), Sphaerotheca, Podosphaera, and the like. As important fungi in this connection, there are mentioned in particular: Erysiphe polyphaga, Podosphaera leucotricha, Uncinula neca tor, and the like.

The active compounds according to the present invention also show an insecticidal and acaricidal activity, particularly against insects and acarids which infest useful plants. It will be realized that in concentrations higher than those fungicidally necessary, as specified hereinabove, the instant active compounds have an inhibitory effect on plant growth.

The active compounds according to the instant invention can be utilized, if desired, in the form of the usual formulations or compositions with conventional inert (i.e. plant compatible or herbicidally inert) pesticidal diluents or extenders, i.e. diluents or extenders of the type usable in conventional pesticidal formulations or compositions, e.g. conventional pesticidal dispersible carrier vehicles, such as solutions, emulsions, suspensions, emulsifiable concentrates, spray powders, pastes, soluble powders, dusting agents, granules, etc. These are prepared in known manner, for instanceby extending the active compounds with conventional pesticidal dispersible liquid diluent carriers and/or dispersible solid carriers optionally with the use of carrier vehicle assistants, e.g. conventional pesticidal surface-active agents, including emulsifying agents and/or dispersing agents, whereby, for example, in the case where water is used as diluent, organic solvents may be added as auxiliary solvents. The following may be chiefly considered for use as conventional carrier vehicles for this purpose: inert dispersible liquid diluent carriers including inert organic solvents, such as aromatic hydrocarbons (e.g. benzene, toluene, xylene, etc.), halogenated, especially chlorinated, aromatic hydrocarbons (e.g. chlorobenzenes, etc.), paraffins (e.g. petroleum fractions), chlorinated aliphatic hydrocarbons (e.g. methylene chloride, etc.), alcohols (e.g. methanol, ethanol, propanol, butanol, etc.), amines (e.g. ethanolamine, etc.), ethers, ether-alcohols (e.g. glycol monomethyl ether, etc.), amides (e.g. dimethyl formamide, etc.), sulfoxides (e.g. dimethyl sulfoxide, etc.), ketones (e.g. acetone, etc.), and/or water; as well as inert dispersible finely divided solid carriers, such as ground natural minerals (e.g. kaolins, alumina, silica, chalk, i.e. calcium carbonate, talc, kieselguhr, etc.) and ground synthetic minerals (e.g. highly dispersed silicic acid, silicates, e.g. alkali silicates, etc.); whereas the following may be chiefly considered for use as conventional carrier vehicle assistants, e.g. surface-active agents, for this purpose: emulsifying agents, such as non-ionic and/or anionic emulsifying agents (e.g. polyethylene oxide esters of fatty acids, polyethylene oxide ethers of fatty alcohols, alkyl sulfonates, aryl sulfonates, etc., and especially alkyl aryl-polyglycol ethers, magnesium stearate, sodium oleate, etc.); and/or dispersing agents, such as lignin, sulfite waste liquors, methyl cellulose, etc.

Such active compounds may be employed alone or in the form of mixtures with one another and/or with such solid and/or liquid dispersible carrier vehicles and/or with other known compatible active agents, especially plant protection agents, such as other fungicides, or herbicides, insecticides, bactericides, etc., if desired, or in the form of particular dosage preparations for specific application made therefrom, such as solutions, emulsions, suspensions, powders, pastes, and granules which are thus ready for use.

As concerns commercially marketed preparations, these generally contemplate carrier composition mixtures in which the active compound is present in an amount substantially between about 0.1-95 percent, and preferably 0.5-90 percent, by weight of the mixture, whereas carrier composition mixtures suitable for direct application or field application generally contemplate those in which the active compound is present in an amount substantially between about 0.00052.0 percent, preferably 0.00l0.05 percent, by weight of the mixture. Thus, the present invention contemplates overall compositions which comprise mixtures of a conventional dispersible carrier vehicle such as (l) a dispersible carrier solid, and/or (2) a dispersible carrier liquid such as an inert organic solvent and/or water preferably including a surface-active effective amount of a carrier vehicle assistant, e.g. a surface-active agent, such as an emulsifying agent and/or a dispersing agent, and an amount of the active compound which is effective for the purpose in question and which is generally about 0.0005-95 percent, and preferably 0.001-95 percent, by weight of the mixture.

Generally, 0.00l0.05 percent by weight concentrations of the active compound are sufficiently effective, although aqueous preparations having concentrations of 0.00052.0 percent by weight of the active com pound are normally used.

The active compound can also be used in accordance with the well-known ultra-low-volume process with good success, i.e. by applying such compound if normally a liquid, or by applying a liquid composition containing thesame, via very effective atomizing equipment, in finely divided form, e.g. average particle diameter of from 50-400 microns, or even less, i.e. mist form, for example by airplane crop spraying techniques. Only up to at most about a few liters/heetare are needed, and often amounts only up to about 1 quart/acre, preferably 2-16 fluid ounces/acre, are sufficient. In this process it is possible to use highly concentrated liquid compositions with said liquid carrier vehicles containing from about 20 to about or percent by weight of the active compound, or even the percent active substance alone, e.g. about 20-100 percent by weight of the active compound.

In particular, the present invention contemplates methods of selectively killing, combating or controlling fungi, which comprises applying to at least one of (a) such fungi and (b) their habitat, i.e. the locus to be protected, a fungicidally effective or toxic amount of the particular active compound of the invention alone or together with a carrier vehicle as noted above. The instant formulations or compositions are applied in the usual manner, for instance by squirting, spraying, atomizing, vaporizing, scattering, dusting, watering, sprinkling, pouring, and the like.

It will be realized, of course, that the concentration of the particular active compound utilized in admixture with the carrier vehicle will depend upon the intended application. Therefore, in special cases, it is possible to go above or below the aforementioned concentration ranges.

The fungicidal effectiveness of the new compounds of the present invention is illustrated, without limitation, by the following examples.

EXAMPLE 1 Erysiphe test Solvent: 4.7 parts by weight acetone Emulsifier: 0.3 part by weight alkylaryl polyglycol ether Water: 95.0 parts by weight The amount of the particular active compound required for the desired final concentration in the spray liquid is mixed with the stated amount of solvent, and the resulting concentrate is diluted with the stated amount of water containing the stated emulsifier.

Young cucumber plants (Delikatess variety) with about three foliage leaves are sprayed with the spray liquid until dripping wet. The cucumber plants remain in a greenhouse for 24 hours to dry. The plants are then, for the purpose of inoculation, dusted with conidia of the fungus Erysiphe polyphaga. The plants are subsequently placed in a greenhouse at 2324C, and at a relative atmospheric humidity of about 75 percent.

After l2 days, the infestation of the cucumber plants is determined as a percentage of the untreated but also inoculated control plants.
